Pass X-350 with Acoustat 2 + 2

Checked it out with my friend. As per the unit's manual, the first 75 watts are class A. Therefore my comment remains the same except it is 75 watts instead of 100.

Thanks for all the replies.
We connected a Pass X-250.5 on the Duetta Sigs and the meter immediately went to the rightcorner went we cranked up the volume.
We did not have much hope for the X-350..
We installed a Krell FPB-600 and it drove the Apogees easily. Very nice combination with a JRDG Coherence Series II and a Krell KPS-20i CD player.

Gee, Pass's web site seems to disagree with the manual:

The article suggest that the Pass X-350.5 leaves Class A at 30 Watts into an 8 Ohm load.

So it will be another "unsolved mystery". My friend drives his 2+2 with ease on his X-350. But yes, the needle meter was also in the right corner on the day he first plugged it. It came back to full center a couple of days after. Full caps !!??

2+2 are not that tough on an amp. They have been tested by a former dealer at 1,97 ohm. Mine drive quite well with a Conrad Johnson 2500A at medium levels and the amp doesn't even get very warm. Never tried at full, don't need to !It's rated at 240 watts. So, it doesn't make any sense that a X-250 can't do the job on 2+2 s. Were the caps full with a couple of days charging before playing it ? Apogee is another story though.

I'm confused. Pass labs X350 or X350.5, completely different amps besides the 150 lbs....
